How can I run a free email service?

Episode 963 (2:21:18)

Tony from La Habra, CA

Tony recently bought a domain name and he wants to start a free email service on his shared web server. Leo says that may be tough because server companies are concerned with spam. He can use a virtual server setup as long as the server company knows what he's doing. Leo recommends SoftLayer. Another option is RackSpace. For software, Leo uses SquirrelMail. Another option is PostFix.
